How to check support on your site
Most analytics show "unsupported browsers" as less than 3-5% of traffic. If your visitors are primarily on modern devices:
- Check your Google Analytics for oldest OS versions (iOS 13, Android 4, Windows 7).
- If these are below 1% of traffic, using WebP with a PNG fallback is safe.
- If these are above 3%, keep serving JPG or PNG as the primary format.
Safe deployment: the picture element
To support both WebP and fallback formats:
<picture> <source srcset="image.webp" type="image/webp"> <source srcset="image.png" type="image/png"> <img src="image.jpg" alt="description"> </picture>
Modern browsers load WebP, older browsers fall back to PNG or JPG. Works in all browsers.
Email and PDF: do not use WebP
If images are embedded in emails or PDFs:
- Outlook (Windows, Mac, web) does not support WebP.
- Most PDF readers do not support WebP.
- Always use JPG or PNG for email attachments and embedded PDFs.
